3.3.6. MultiSolver

MultiSolver runs a sequence of solver blocks in order. When one solver finishes (deactivates the model), MultiSolver activates the next solver and continues until all are complete.

3.3.6.1. Overview

Solver type: MultiSolver

Orchestration: imports and constructs solver classes by name
Progression: advances to the next solver when globdat.active becomes false

3.3.6.2. Parameters

3.3.6.2.1. Mandatory Parameters

Parameter	Description
`type`	Must be set to `"MultiSolver"`
`solvers`	List of solver block names to run in order

3.3.6.3. Solver Blocks

For each name in solvers, define a block with at least a type:

Parameter	Description
`type`	Solver class name under `pyfem.solvers` (e.g., `NonlinearSolver`)
Other parameters	Solver-specific options (see their documentation)

3.3.6.4. Examples

Run a nonlinear solve followed by a modal analysis:

solver =
{
  type    = "MultiSolver";
  solvers = [ "nl", "modal" ];
};

nl = { type = "NonlinearSolver"; maxCycle = 10; };
modal = { type = "DynEigSolver"; eigenCount = 5; };
